Hello M
The 1911 census shows AY Nutt, his wife, Ida and Maude living at Garden House, Windsor Castle.
I think the family left when he HAD to retire soon after. His retirement came as a big shock to AY. I think he felt he still had a lot of work left in him! He didn't see it coming with his 65th birthday.
He went on to build the first concrete church in Goldthorpe, plus many other projects like the War Memorial in you post.
I had not seen the article, so thank you for that. But sadly no photo. Maybe someone from Rootchat who lives in Slough could help!
